ACETYLEN'E-LAMP.

Specification of Letters Patent. Patented Feb. 25, 1919.

Application filed September 3, 1918. Serial No. 252,297.

To all whom it may concern:

Be it known that I, AUGIE L. HANSEN, a citizen of the United States, and a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Acetylene.- Lamps, of which the following is a specification. a

My invention relates to gas lamps and particularly to improved pyrophoric ignition mechanism therefor.

Although my invention is applicable to different types of gas lamps and to gas burners, it is of particular utility in miners acetylene cap lamps. Amongthe important objects of the invention are to provide ignition mechanism which can be readily applied to lamps or burners; to provide such construction that the pyrophoric sparks will be deflected across the path of the gas issuing from the tip orifice; to provide construction which will break up the solid stream of gas from the tip orifice and will. spread the gas to offer greater ignition area and range forthe pyrophoric sparks; to provide construction by means of which the pyrophoric material can be heated by the ignited flame to dry it in caseit should be rendered useless by moisture; to provide constructionwhich will enable operation'of the mechanism without contact of the fingers or hand with the serrated 'pyrophoric material engaging surface; to provide construction which will enable the use .of a long pyrophoric material cartridge; and to provide mechanism which. can. be readily and accurately operated by onehand with? out removing the lamp from the miners cap.

The above and other features of the invention are clearly disclosed in the following specification and on the accompanying drawing, in which drawing 7 Figure 1 is a front elevational view of a miners cap lamp, I

Fig. 2 is a side elevational view with the upper part of the lamp in section on plane 2-2, Fig. 1, V g M Fig. 3 is a sectional viewon plane 3.-3, Fig. 2, and Y Fig. 4 is an enlarged sectional view ofthe serrated baffle member, on plane 44,'Fig. 1. The lamp shown is an ordinary miners cap lamp comprising the water container 10 and the carbid cup 11 having detachable threaded engagement therewith, The water tube 12 is secured'to the upper and lower walls of the water container and extends down into the carbid cup, the valve rod13 the tube end and the lower end of the valve 7 rod having the valve surface15 cooperating with the valve seat 16 at the bottom of the water tube.v The lever 17 permits turning of the valve rod to control the water flow. A reflector 18 forms the front wall of the water container and the gas tube 19 extends through the bottom wall of the water container to receive the gas from the carbid cup, the outer end of the gas tube extending axially throughthe reflector and supporting the ne tip 20 which has the small gas orifice 21. The clamp 22 and the hook 23 at the rear of the water container enables the lamp to be supported on a miners cap in the well known manner.

Describing now the pyrophoric ignition mechanism, a stud 24 extends forwardly from the reflector parallel with and at one side of the tip and on the front end of this stud is pivoted the plate 25 by means of the screw 26.

Between the stud 2 1 and the tip 20' and above the tip a barrel or'tube 27 extends through the reflector and the water container and is secured .to the rear wall of the water container. The front end of the barrel terminates just a short. distance behind the plane ofv the plate 25 and the compression spring 28 confined within the barrel ,between the adjustable screw 29 and the pyro-v phoric material cartridge 30, the spring tending to pressthe front end of the cartridge against the plate 25. The .plate 25 has the arm 31 extending outwardly there from across the reflector edge, and a coiled spring 32 supported on the stud 24: and

anchored at its ends to the arm 31 and. the barrel 27 tends to rotate the plate to hold the arm 31 against. the stop 33 secured to the reflector flange near the top of the lamp."

part of the platewill pass in front of the tip outlet. The T 1 112? fa of the Platehas the serrations or teeth 85 which, when the lever is released and the plate returned by the spring, rub over the end of the pyrophoric cartridge to cause sparks. The incandescent pyrophoric material particles are thrown by'the teeth across the tip'outlet into the issuing gas. Also While these sparks are beingprojected, the plate is 1n front of the tip outlet and thegas, which would otherwise issue under pressure in a thingstream, is dispersed and spread within the, reflector so as to offer a more extended 'x 'olume to the sparks, and ignition isthus ss red ith u equi s r manip lations of the plate rotating arm.

7 My improved ignition mechanism has decided advantages .over the wheel type igniting meohanism in which a serrated wheel against whieh pyrophoric material is pressed is ur ed y th fi ge o palm- Inh fir t plaq suehwheel becomes moistened by such engagement and [when it ismoist the pyrophor-ic material becomes moistened and will not properly function. With my improved me hani m t e e ate pla s tate y am an i and hsPy PhQ te arewell protected against'moisture. However, should'tl pyrophoric material become moist it can be readily dried and fitted for e v-iqe by i s i g he 2 .111. nd ro at n the plate to %ring it in front of the tip orifice so that the flame will be deflected against the end of the barrel and the pyrophori naterial therein the heat rapidly drying the pyrophoric material. Again, in my im; proved mechanism, the sparking operation is more uniform, the spring which returns the plate acting always with the same force, .whereas with the ordinary sparking wheel which must be rotated by the finger or hand, the. operation is erratic. It will also be noted that my improved mechanism a long barrel is provided in which a long cartridge of pyr phor-ic material is accommodated. In

arrangements of i the prior art short cartr dges were used wh ch readily Jam in the b-arr eland are soon used up, requiring frequent recharging.
